Here's the list (I'm sure the guy I played against had a couple different cards, but this is my list):
2x Unleash the Hounds
2x Stonetusk Boar
2x Timber Wolf
2x Young Dragonhawk
2x Explosive Trap
2x Ironbeak Owl
2x Novice Engineer
2x Starving Buzzard
2x Eaglehorn Bow
2x Deadly Shot
2x Kill Command
The Concept is pretty simple: play it as if it's a control deck, using your traps and bow to take out minions early on, paying special attention to minions with taunt. When time allows, use the cards that give draw power to search the deck for all the one-cost minions (especially Timber Wolf and Young Dragonhawk) and at least one copy of Unleash the Hounds. When you've managed to chip the hero down far enough (and there's no massive taunter on board), play all the one-cost minions and Unleash the Hounds to deal huge damage in one turn.
This thing works beautifully. The only game I've lost so far was against someone who played a massive minion on turn six, then made it a taunter on turn seven, and I didn't have destruction in hand. I'm considering running the Ironbeak Owl just in case I run into a similar situation again.
A few notes on the cards:
-not only does Flare draw you cards, but it also works amazingly well for those hunter vs. hunter matchups where they played a secret. You REALLY don't want to run into an Explosive Trap on the turn you play all your 1-health minions.
-around turn eight or so, even if you don't have Unleash the Hounds in your hand, two Starving Buzzards plus three one-cost minions will almost certainly get you one copy. If you time it right, you can get all the cards you need from your draw power, even if you don't have all the pieces at the start of the turn.
-I rarely play Bloodfen Raptor on the turn when I use Unleash the Hounds, unless I have a second copy of Unleash in hand for later play. I mainly use Bloodfen to create a threat that forces the opponent to burn cards on him (instead of on my hero), as well as to get the extra damage out of Kill Command.
Anyone else run into (or tried) something similar? How did it fare for you? I've been playing a lot (too much) over the past week, and this is still by far the strongest deck I've seen, when played properly.
EDIT: took out the Bloodfen Raptors and added in Ironbeak Owls two weeks ago. Updating this post for those who read nothing of the thread besides this post.
